"Full-featured vulnerability scanner for your network infrastructure"
Written By

Nessus is a program that all IT professionals should use, specially those in charge of IT security: it is a full-featured vulnerability scanner that allows you to analyze your network assets and detect potential security issues. It is not in any way a replacement for ethical hackers of other IT security specialists, but it is a great application to make the first steps in a better protected network.

Nessus can detect default configurations, weak passwords, out-of-date programs (like a server OS or a database), and more. It can also detect a systems vulnerability to a (Dedicated) Denial Of Service attack, and can even call in 'Hydra' to perform a dictionary attack on your passwords.

Its interface is simple, friendly and well-organized. You can scan a single host, the DMZ and even the complete internal network. Nessus is by far one of the best tools for penetration testing and other security tests.
